JRS Engineering provides roof design and consulting services throughout the Pacific Northwest. Since the founding JRS in 1998, we have become a leader in the roof consulting field. Our goal for all projects is to work with property managers, owners, and contractors to cultivate high-performance, aesthetically rich buildings that deliver greater durability, energy performance and value to our clients.
JRS combines a thorough knowledge of building science with a practical understanding of the construction process to implement technically-sound, cost-effective roofing solutions.

ENERGY, SUSTAINABILITY & GREEN DESIGN
We place a high priority on pursuing sustainable design and construction
